cassia, (Cinnamomun cassia), tree of the family Lauraceae and the spice made from its aromatic bark. The bark of cassia Cinnamomum cassia is similar to that of true cinnamon (Cinnamomum verum), to which cassia is closely related. Cassia bark has a more pungent, less delicate flavour and is thicker than cinnamon bark. It contains 1 to 2 percent oil of cassia, a volatile oil the principal component of which is cinnamic aldehyde. Cassia bark is used as a flavouring in cooking and particularly in liqueurs and chocolate. Southern Europeans generally prefer it to true cinnamon, and in North America ground cinnamon is commonly sold without distinction as to the species from which the bark is obtained. It is one of the five dried spices—including fennel, cloves, star anise, and Sichuan pepper—that make up the famed Chinese five-spice powder.
Cassia bark is peeled from stems and branches and set aside to dry. Some varieties are scraped. While drying, the bark curls into quills. The colour varies from light reddish brown for the thin, scraped bark to gray for the thick, unscraped bark. Ground cassia is reddish brown in colour. Chinese cassia—one of the ingredients in China’s famed five spice powder—is less aromatic than that from Vietnam and Indonesia. Cassia from all three countries has a sweet, aromatic, and pungent flavour. Vietnamese, or Saigon, cassia is particularly highly esteemed.
Cassia buds, the dried unripe fruits of Cinnamomum cassia and Cinnamomum loureirii, have a cinnamon-like aroma and a warm, sweet, pungent taste akin to that of cassia bark. The whole buds are added to foods for flavouring. The brown immature fruit is snugly held in a cuplike, hard, wrinkled, grayish brown calyx (the whole commonly called a bud) varying in size but ordinarily 11 mm (0.4 inch) long, including the calyx tube; the upper part of the bud may be about 6 mm (0.25 inch) in diameter.
Confusion sometimes arises with another group of plants because Cassia is the generic name of an extensive genus of leguminous plants, which, in addition to various other medicinal products, is the source of senna leaves.
